The Department shall by rule prescribe standards for determination of the amount of bonds. Such standards shall include the probable difficulty of reclamation, topography, geology, hydrology, revegetation potential, and other standards related to the purposes of this Act. In no case shall the bond for the entire area under one permit be less than the greater of $600 per acre or $10,000.
